Encyclopedia: Medieval Cosmology and Worldview Medieval cosmology was centered around the concept of the Ptolemaic universe, named after Greek astronomer Ptolemy (ca. 150 CE). In this geocentric (earth-centered) model, the earth was the motionless center of the universe, with the rest of the universe revolving around it in spheres. Ptolemy's work was based on Aristotle's (384-322 BCE) idea of an ordered universe, divided into the sublunary, or earthly, region which was changeable and corruptible, and the heavenly region, which was immutable and perfect.

Centermost in this cosmology was the Earth.

Then there is the rich history and cultural heritage of medieval towns such as Dubrovnik, Split and Sibenik. But the well-deserved popularity also depends on the protected natural areas, which make up some ten per cent of the country's area.
